Myinvention relates to travelers for use upon the rings of spinning or twisting machines.y Y f- The essentialfobjects ofV my` invention are i to provide means in the travelerkfor lubricating the ring upon whichthe-traveler moves;

1 i to automatically discharge the lubricant uponk the ring; to affordl abroad area of distribu s tion of the lubricant; to attainthese ends in V a sim le and'inexpensive structure; and to provi e a novel and economical' method of constructing the traveler@ Y r v Tothe above ends essentially my invention consists in such parts and vcombinations vof V parts, and in'such steps and in suchcombinations of steps, as fallwithin the scopeof the appended claims. ,A

In the accompanying drawings which form a part of this specification, Y

Figure 1 is a perspective view of the tubular blank froml which my traveler is formed,

Fi res 3 and 4, sections of the same on lindes 3-3vand 4--4 respectively of Figure 2, p Figure 5, a front elevation of the complete traveler mounted in' running position upon a ring of the T-type, the4 latter being shown in c cross section.V

Like reference characters indicateV like parts throughout the views.

.Mytraveler is formed from a cylindrical metallic blank 8 cut from a length of hollow wire, shown in Figure 1, provided with a cylindrical axial opening 9 extending throughout its length, and with a hole 10 'extending fromits periphery to the opening 9 midway the length of the blank.

This tubular member is by suitable tools bent whereby its intermediate portion is formed into an arched or substantially semil circular/body 13 with a cylindrical bore or chamber 9, and its end portions are formed 40 into inwardly directed, horizontal horns 14 what, to increase their breadth whereby their integralwith the body and by compression i bores ,or passages 16, continuous with the 'i chamberjQ,V are transversely substantially elliptical incross'section. i

" In Figure 5 is shown my traveler in running position impelled by the thread or yarn 18, extending from the rolls to the bobbin or spool, moving upon. ythe ring 2() of the horizontal type, comprising the usual base 21, web

22, and T flange 23.V The tops of the horns 14 n Y are" in 'contact with vthe lower yfaces of the flange; and the free extremities of the former are adjacent or in contact with the web 22.

Av solid fusible lubricant such as grease is A manually injected through the hole 1() into the portions 9 and 16 of the axial passage f preferablyilling the same to or adjacent the free extremities of the horns. The heat genc eratedkin the traveler by its tfrictional con-y tact-with the :ring andthe yarn gradually liquelies the lubricant, which is slowly fed or Y discharged upon the lower faces of the flange 23 and upon the sides of the web 22, thus preventing both .wear of the traveler, and the generation of a warping temperature of the latter.

While: improved tubular horns ofcircular or other cross sectional shapes diiering from that described,

it is found thateventsuperior results are at` tained when the horns are flattened. w It will be observed that the lubricant is automatically fed'from thetraveler, rand that ythe constructionv from a tubular blank inring'comprising an arched body provided results are attained by the with a central longitudinally disposed chamber and with a hole at the apex of therbody communicating with the chamber, and horns integraly with the body provided with passages continuous with the chamber.
